Light the Cities of the Future
A previously unlit cycle path in the Netherlands has recently drawn our attention. It has been resurfaced with a material that consists of thousands of shining stones in order to create a well-lit route. The Van Gogh Path, so called after the artist who lived in the town of Nuenen in 1883, combines the traditional with the contemporary in a gesture that acknowledge ledges Van Gingh’ masterpiece The Starry Night, but also shows the way ahead for city lighting. The Van Gogh Path is not a single case; it is not difficult to foresee a time when natural materials could help light the cities of the future.
Why should we care about city lighting? What’s wrong with current electrical city lighting anyway? Well, the problem that it causes is two-fold. First, of course, electrical lighting in most cities comes from non-renewable resources. According to the International Energy Agency, almost 20% of global electricity is consumed for lighting, which is responsible for high levels of carbon emissions. But there’s also the belief that electrical light itself is a form of pollution by destroying our view of the night sky.
From the above reasons, then, it seems wise to investigate other approaches. The city of Glasgow is attempting to use intelligent street lighting to monitor how citizens interact with the urban landscape and minimize electrical consumption and thus emissions. This “Smart City approach” is seen by many as the way of the future, but some designers aren’t convinced. They are pioneering the altogether more original approach of using materials from the natural world in order to replace electrical light entirely. They believe that this new “technology” can one day completely replace microchips and digital systems as we find better ways of making use of the light-producing mechanisms (制) that already exist in the natural world.

8 . Could your dog be prone to a fatal disease? Is your new shelter pup part beagle or boxer? Many pet owners seek answers to these questions, and as a result, direct-to-consumer dog DNA testing is booming.
Human interfering with dog DNA has long been the driving factor behind dogs’ breed diversity — or lack thereof. But a dog’s DNA can also be used to confirm their lineage (血统) or identify their breed, a boon for pet owners on the lookout for breed-specific health or behavioral challenges or those looking to confirm their dog really has the heritage claimed by a breeder or seller. During DNA analysis, labs sequence the dog’s DNA and look for similarities with a dataset of identified dog breeds.
But breed identification isn’t as simple as it might seem. In a study published in the Journal of the American Veterinary Medical Association last month, scientists looked into the accuracy of breed prediction in commercially available DNA tests that required a photo of the dog in addition to its DNA sample. The results were mixed, says Casey Greene, a professor who co-authored the study.
“Most tests could accurately distinguish the breed of purebred dogs,” says Greene. But the analysis suggested that some testing companies might rely on the photo more than the dog’s actual genetics — and revealed big differences between companies’ business practices and the genetic datasets they use to determine dog breeds.
The researchers submitted photos and DNA of 12 purebred dogs to a total of six commercial canine (犬的) ancestry identification services. Since each pup was purebred and possessed extensive American Kennel Club paperwork, the researchers knew their breed conclusively—but in some cases they provided a photo of a different dog to see if the photo influenced the DNA results. One of the companies misidentified a purebred Chinese crested dog — almost entirely hairless — as a long-haired Brittany spaniel, seemingly based on the photo alone. The other five did identify the registered breed correctly, but often gave different predictions for other “ancestor” breeds in dogs whose DNA suggested mixed breeding in prior generations. The researchers concluded that veterinarians and pet owners alike should “approach direct-to-consumer tests with caution” given the lack of industry standardization and at least one company’s reliance on photographs instead of DNA analysis.
Despite these concerns, though. dog DNA seems headed for a golden age — and the insights revealed through further study of Fido’s genome (基因组) have already reached far beyond the doghouse. Domesticated dogs have emerged as surprising superstars in medical research that benefits humans. According to researchers, that’s just the beginning. With implications ranging from entertaining to consequential, there’s no telling what dog DNA will continue to unleash.

IN CONTEXT BRANCH Geology BEFORE 6th century BCE The Greek thinker Thales of Miletus notes magnetic rocks, or lodestones (天然磁石). 1st century CE Chinese diviners make primitive compasses with iron spoon that can turn around to point south. 1269 French scholar Pierre de Maricourt sets out the basic laws of magnetic attraction, repulsion, and poles. AFTER 1824 French mathematician Siméon Poisson models the forces in a magnetic field. 1940s American physicist Walter Maurice Elsasser attributes Earth’s magnetic field to iron swirling in its outer core as the planet rotates. 1958 Explorer 1 space mission shows Earth’s magnetic field extending far out into space. | By the late 1500s, ships’ captains already relied on magnetic compasses to maintain their course across the oceans. Yet no one knew how they worked. Some thought the compass needle was attracted to the North Star, others that it was drawn to magnetic mountains in the Arctic. It was English physician William Gilbert who discovered that Earth itself is magnetic. Stronger reasons are obtained from sure experiments and demonstrated arguments than from probable conjectures (推测) and the opinions of philosophical speculators. William GilbertGilbert’s breakthrough came not from a flash of inspiration, but from 17 years of careful experiment. He learned all he could from ships’ captains and compass makers, and then he made a model globe, or “terrella,” out of the magnetic rock lodestone and tested compass needles against it. The needles reacted around the terrella just as ships’ compasses did on a larger scale—showing the same patterns of declination (pointing slightly away from true north at the geographic pole, which differs from magnetic north) and inclination (tilting down from the horizontal toward the globe). Gilbert concluded, rightly, that the entire planet is a magnet and has a core of iron. He published his ideas in the book De Magnete (On the Magnet) in 1600, causing a sensation. Johannes Kepler and Galileo, in particular, were inspired by his suggestion that Earth is not fixed to rotating celestial spheres, as most people still thought, but is made to spin by the invisible force of its own magnetism. |

“There does appear to be a faster rate of automation, and a slower rate of augmentation, in the last four decades. from 1980 to the present, than in the four decades
The study finds that overall, about 60 percent of jobs in the U.S. represent new types of work, which have been created since 1940. To determine this, Autor and his colleagues
From about 1940 through 1980, for instance, jobs like elevator operator and typesetter tended to get automated. But at the same time, more workers filled roles such as shipping and receiving clerks, buyers and department
Ultimately, the research suggests that the negative effects of automation on employment were more than twice as great in the 1980-2018 period as in the 1940-1980 period. There was a more
